1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveα-1 antitrypsin deficiency (AATD) is an inherited liver disease characterized by the "Z" mutations, which can cause pulmonary emphysema and liver fibrosis. Transplantation of the organ (i.e., the lung/liver) is the best treatment method, however, the scarcity of suitable donors limits its application. The cell transplantation technique poses an alternative way of combating liver failure.

methodsHepatic specific differentiation of the human induced pluripotent stem cells (iPSCs) was initiated with 100 ng/mL activin A, followed by 20 ng/mL of BMP-4 and 10 ng/mL of FGF-2. The cells were transplanted into the livers of AATD transgenic mice using intra-splenic injections. FK506 was used as an immunosuppressor. At 1, 3, and 6 months post-transplantation, the human serum albumin (HSA) levels and its DNA contents, and the mice serum and liver tissues were measured using enzyme-linked immunosorbent assays (ELISA), polymerase chain reactions (PCR), and immunohistochemistry to estimate the repopulation of the hepatic-specified cells.

resultsPost transplantation, the hepatic-specified cells were found to be successfully and progressively repopulated in the transgenic mice livers. Additionally, the hepatic-specified cells did not display any carcinogenicity, as confirmed by the absence of any tumors on the animals.

conclusionWe provide a time saving and low cost method of transplanting hepatic-specified cells into the livers of AATD mice without any risk of carcinogenicity, a method that may be a potential option for the treatment of AATD.
